On-page optimizations

Google said:

The project looked at the main pages of 100 different Google products, measuring them across a dozen common optimization categories. Future iterations of the project might look at deeper Google product web pages as well as international ones. We released the report card within Google last month and since then a good number of teams have taken action on it or plan to.
